Rapidly Modulated and Oscillated Laser Beam Distance Sensor

Many discussion around divergence, rs232, distance, laser divergence, and distance measurement sensor are presented in the datasheet. Inside this datasheet we can get description related to laser, output, analog, and measurement sensor.

This datasheet tells us info like beam, distance measurement, measurement, and sensor. These are selected from this datasheet:

The AR3000 distance measurement sensor is Acuity’s longest-range model for cranes, process mointoring and fill levels in containers and silos. Its eye-safe laser and robust enclosure design make it a versatile choice for industrial measuring applications. A special version of the AR3000 can be used as a laser altimeter. AR3000 Distance Measurement Sensor Principles of Operation The AR3000 sensor is a time-of-flight sensor that measures distance by a rapidly-modulated and collimated laser beam that creates a spot on a target surface. Components of the reflected light signal are collected by a lens and focused onto a photodiode within the sensor unit
